Description
Technical field
The utility model belongs to PTC heater field, and in particular to the PTC heater of wall electric heater.
Background technique
The pollution of winter coal heating is very big, and in order to improve air quality, northern country starts popularization coal and changes electric policy, because of north
The existing heating in side is mostly hot-water heating heating system, with efficient ptc heater in existing water-heating system, replaces combustion
The boiler of coal.
The bore of existing water stream channel is too small, generally in 5mm or so, and because of northern water quality inferiority, so as to cause in water
Impurity be easy accumulation fouling, and make the obstructed of water flow, can not be by heat into emitting air in addition, thermal conductivity is bad.
Utility model content
The purpose of this utility model is to provide the PTC heater of wall electric heater, using heavy caliber water flow passage,
Reduce water resistance, it is not easy to block.
The purpose of this utility model is to provide the PTC heaters of wall electric heater to add in conjunction with PTC fire-bar
A hot electrified regulation heat is transmitted in flowing water through metal flow passage, and thermal conductivity is more preferable.
The purpose of this utility model is to provide the PTC heaters of wall electric heater to play guarantor in conjunction with heat-preservation cotton
Temperature effect.
The purpose of this utility model is to provide the PTC heaters of wall electric heater to be risen using aluminum alloy casing
Decoration integrally acts on.
In order to achieve the above object, the major technique solution of the utility model is to provide the PTC hair of wall electric heater
Hot body, which is characterized in that the PTC heater includes water flow passage, PTC fire-bar, heat-preservation cotton and shell, outside the water flow passage
Wall lays the PTC fire-bar, wraps up the heat-preservation cotton outside the PTC fire-bar, the heat-preservation cotton is externally provided with the shell, institute
It states water flow passage both ends and is equipped with water nozzle, the PTC fire-bar is equipped with string holes.
In some instances, the middle part of the water nozzle is popped one's head in equipped with water temperature.
In some instances, the water flow passage be square cylinder and it is interior be equipped with circular through hole.
In some instances, the connecting pin of the water flow passage and the water nozzle is equipped with seal groove, is equipped in the seal groove
Sealing ring.
In some instances, the water nozzle is selected from metal water nozzle.
In some instances, the shell both ends are equipped with end cap.
In some instances, the end cap is equipped at least two installation feet.
In some instances, the shell is selected from aluminum alloy casing.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of an embodiment of the present invention,
In figure: water flow passage 1, PTC fire-bar 2, heat-preservation cotton 3, shell 4, water temperature probe 5, water nozzle 6, end cap 7, installation foot 8,
Sealing ring 9.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
Example example one:
As shown in Figure 1, a kind of PTC heater of wall electric heater, including water flow passage 1, PTC fire-bar 2, heat-preservation cotton
3 and shell 4, water flow passage 1 is square the cylinder of circular hole, i.e., water flow passage be square cylinder and it is interior be equipped with circular through hole, compared to
For existing water flow passage is oblate, the area of water flow is increased, further, since in view of the water quality in the north is relatively poor,
Mix impurity in water, be easy fouling, block in order to prevent, set heavy caliber water flow passage for water flow passage 1, the present embodiment it is big
Bore is set as 30mm, but heavy caliber is not limited only to 30mm, it is understood that for existing bore, is greater than existing water
The bore of runner, heavy caliber can also reduce water resistance, and water flow is more smooth, and the PTC fire-bar 2 is four, be sticked respectively
On four walls of water flow passage 1, heat is transmitted to through four walls of water flow passage 1 and to flow in water flow passage 1 by 2 electrified regulation of PTC fire-bar
In water, so that carrying out electric energy is converted to thermal energy conduction, hot water through room radiator heat-dissipation into air, outside the PTC fire-bar 2
The heat-preservation cotton 3 is wrapped up, heat preservation is played the role of, the heat-preservation cotton 3 is externally provided with the shell 4, and the shell 4 is selected from aluminium alloy
Shell 4 plays decoration one, and 1 both ends of water flow passage are equipped with water nozzle 6, and water nozzle 6 is made of metal, the company of water nozzle 6
It connects end and is equipped with external screw thread, and connect by screw with the port of water flow passage 1, the connecting pin of the water nozzle 6 is additionally provided with seal groove, institute
It states and is provided with sealing ring 9 in seal groove, the sealing ring 9 is made of silica gel, guarantees that water will not leak, the middle part of the water nozzle 6
One water temperature probe 5 is installed, for measuring the temperature of water, the both ends of the shell 4 are equipped with end cap 7, and the water nozzle 6 passes through
End cap 7 simultaneously exposes, the connection of the end cap 7 fixing shell 4 and water nozzle 6, and the end cap 7 sets that there are two installation foot 8, installation feet 8
